Why many in law enforcement oppose California’s Proposition 64: A growing number of Southern California law enforcement organizations and leaders are voicing objections to a state ballot measure that would legalize recreational marijuana, saying it would make the state less safe. “I’m vehemently opposed to it,” Orange County Sheriff Sandra Hutchens said. “I think that it would be a terrible move for California to make.” San Bernardino County District Attorney Mike Ramos said the initiative to legalize marijuana “will do nothing to curb black-market activity in California.” He is one of several police officials who is actively opposing the measure, a group that includes the Riverside Sheriffs’ Association, the Association for Los Angeles Deputy Sheriffs and the California Police Chiefs Association. –Report by The Orange County Register’s Brooke Edwards Staggs
